Sealing device for a human-machine dialogue element

Abstract

A sealing device for a human-machine dialogue element intended to be fixed through a wall, the device including a seal formed in a ring around an axis, the seal including a first annular edge and a second annular edge. The second edge follows a path including a plurality of chicanes so as to form at least one concave part delimiting a bearing zone on one face of the seal and at least one convex part delimiting a disengagement zone on the face of the seal to circumvent a positioning element of the seal.

The invention claimed is: 
     
       1. A sealing device for a human-machine dialogue element adapted to be fixed through a wall, said device comprising a seal formed in a ring around an axis, said seal comprising:
 a first annular part comprising at least one positioning element of the seal adapted to cooperate with said human-machine dialogue element to limit a rotation of the seal about said axis, and 
 a sealing second annular part comprising a first face and a second face, 
 wherein: 
 the seal includes a first annular edge formed around said axis projecting from said first face and a second annular edge formed around said axis projecting from said second face, and 
 the second annular edge follows a path including a plurality of chicanes so as to form at least one concave part delimiting a bearing zone on said second face and at least one convex part delimiting a first disengagement zone on said second face to circumvent said at least one positioning element. 
 
     
     
       2. The device according to  claim 1 , wherein said first annular part takes the form of a belt and in that said sealing second annular part forms a flange around said belt. 
     
     
       3. The device according to  claim 2 , wherein said belt comprises an internal first face and an external second face, and wherein said at least one positioning element comprises a hollow formed in said internal first face forming a protuberance on said external second face. 
     
     
       4. The device according to  claim 1 , wherein the first annular edge comprises at least one chicane delimiting a second disengagement zone on said first face to circumvent said at least one positioning element. 
     
     
       5. A human-machine dialogue assembly, comprising the human-machine dialogue element provided with a tubular body surmounted by a flange, and the sealing device as defined in  claim 1 , said seal being adapted to surround said tubular body of the human-machine dialogue element with said first annular part and to bear against the flange through said first annular edge. 
     
     
       6. The assembly according to  claim 5 , further comprising an identification device comprising at least one tongue adapted to bear on said bearing zone of the first face. 
     
     
       7. The assembly according to  claim 6 , wherein the identification device comprises a first part having an opening arranged at a periphery of said flange of the human-machine dialogue element and a second part carrying said at least one tongue. 
     
     
       8. The assembly according to  claim 7 , wherein the first part of the identification device comprises a housing adapted to receive an identification label. 
     
     
       9. The assembly according to  claim 7 , wherein the first part of the identification device comprises a casing, and wherein the second part comprises a plate assembled onto said casing. 
     
     
       10. The assembly according to  claim 9 , wherein the plate comprises a routed opening on an edge of which is formed said at least one tongue. 
     
     
       11. The assembly according to  claim 9 , wherein the casing and the plate are assembled together by peening or overmoulding.
